摘要: [目的] 为探索高光谱遥感影像动态集成过程中多特征信息利用的有效性,本文提出了一种基于多特征的高光谱遥感动态集成算法(MDE)。[方法] 该算法首先提取出高光谱遥感影像的光谱特征、Gabor特征、局部二值模式(LBP)特征和扩展形态学多属性剖面特征(EMAPs);然后根据每个测试样本的特点,动态地选择最佳的特征预测结果参与集成决策;最后利用Salinas和Indian Pines两组高光谱遥感影像作为试验数据,对MDE算法的性能进行评价与分析。[结果] 试验结果表明,MDE算法在Salinas数据上总体精度达到96.89%,在Indian Pines数据上总体精度达到94.99%。[结论] 与其他对比算法相比,本文算法具有更稳定优异的分类表现。

Abstract: [Purposes] In order to use spectral information and spatial information in hyperspectral remote sensing images,a multi-feature dynamic ensemble method (MDE)based on hyperspectral remote sensing is proposed. [Methods] Firstly,the algorithm extracts spectral features,Gabor features,LBP features and EMAPs features of hyperspectral remote sensing images.Then,according to the characteristics of each test sample,the best feature prediction results are dynamically selected to participate in the integrated decision-making.Finally,two datasets of AVIRIS (airbone visible infrared Imaging spectrometer)sensor are used to evaluate the performance of the proposed algorithm. [Findings] The results show that the overall accuracy of MDE algorithm is up to 96.89% in Salinas dataset and 94.99% in Indian Pines dataset. [Conclusions] Compared with other methods,MDE can provide excellent and stable classification results.
